IMPROVEMENT IN LAND-ROLLERS.

Specication forming part of Letters Patent No. 157,327, dated December1, 1874; application filed April 25, 1874.

To all whom Iit may concern:

Beit known that I, BENJAMIN S. HEALY, of Cohocton, in the county ofSteuben and State of New York, have invented a new and usefulImprovement in Land-Roller, of which the following is a specification:

Figure lis a vertical section of my improved roller. Fig. 2 is a rearview of the same. Fig. 3 is a top view of the same.

Similar letters of reference indicate corresponding parts. A

The invention will first be fully described, and then pointed out in theclaim.

A B C is the roller, which is made in three parts or sections. Theforward and longer parts A B are placed in line with and at a littledistance from each other. The rear and shorter part C is placed directlyin the rear of the space between the parts A B, and is made of such alength that its path may overlap the paths of the parts A B, so that thewhole surface of the ground may be rolled. D is the frame-work of theroller, which is made in such a form as to surround the three parts ofsaid roller, as shown in Fig. 3. rlhe frame D is made in two equalparts, which are hinged to each other in the central line of themachine, so that its side parts may rise and fall to ad- `justthemselves to the surface of the ground. The journalsof the rear part Cof the roller revolve in bearings or `journal-boxes or blocks E, whichrock in staples or other keepers attached to the longitudinal bars ofthe rear part of the frame D, so that the rise and fall of either end ofthe frame D will not effect the rotation of the said part C of theroller. F is the tongue, the rear end of which is hinged to the middlepart of the frame D, in the line of its hinges. The tongue F passesthrough a long keeper or slotted guide, G, attached to the middle partof the front of the frame D, so that the forward end of the tongue mayhave a free vertical movement, to relieve the horses necks from havingto sustain any downward pressure, and thus make their work eas- 1er. akeeper attached to the tongue F, and is pivoted to a bolt, I, whichpasses through a hole in said double-tree and through a longitudinalslot in said tongue and keeper. J are draftbars, the rear ends .of whichare hooked into staples or eyes attached to the front bar ofthe frame D,upon the opposite sides of and equally distant from its forward hinge.rIhe forward ends of the draft-bars J are pivoted to the rear corners ofa plate, K, which is inserted in a horizontal slot in the center ofthedouble-tree H, and has a hole formed through it, through which thedouble-tree bolt I passes.

By this arrangement the draft will always be applied to the front partof the frame l), whatever position the tongue F may have.

The rearwardly-projeoting part of the frame D is strengthened by theinclined braces L, as shown in Fig. 3.

. Having thus described my invention, I claim as new and desire tosecure by Letters Pat- 611t- The combination, with frame and slottedhinged tongue, of the single-tree H, bolt I,

plate K, and rods J J, as and for the purpose specilied.
